Deionizers are crucial pieces of machinery that use the Eco-Tecan ion exchange process to remove dissolved ionic salts and minerals from a solution. They are also referred to as demineralizers, ion exchangers, or DI systems. Deionizers are used for a variety of tasks, including the treatment of waste water, the production of potable water for marine vessels, and the production of pure water for delicate operations like nuclear power generation, semiconductor manufacturing, and pharmaceutical production. They are frequently used in conjunction with reverse osmosis systems, which are used to treat brackish or seawater.

Mixed Bed Units:-

are an Excel Filtration method used where superior water quality is needed. They are typically the last treatment step in the water treatment process train. They are normally positioned downstream of either individual two-bed working ion exchange units or reverse osmosis systems, further treating the effluent of these demineralizers. For low TDS (Total Dissolved Solids) waters, they can be used as standalone ion exchange units. In this application they are often referred to as “Working Mixed Beds”. In condensate polishing applications, you can use Mixed Bed Ion Exchange to remove condensate contamination before reuse Mixed Beds are ion exchangers that have both Cation and Anion resins, mixed in a single vessel. The resin bed is in the both H-OH form. These units are normally designed so that they can be automatically operated, with all the necessary internals, instruments, components and controls. Each unit is mounted on a rigid, structural steel skid base. The last traces of TDS and silica can be removed on a resin bed where highly regenerated strong acid cation and strong base anion resins are mixed. Mixed bed units deliver an excellent treated water quality, but are complicated to regenerate, as the resins must first be separated by back washing before regeneration. 


During the service cycle, water enters the unit through the inlet distributor at the top of the vessel, and is evenly distributed across the resin bed. As the water flows through the resin bed, its ionic contaminants are exchanged for H and OH ions on the resin beads. This removes the ionic contaminants from the water, producing highly purified Demineralized water. The treated water then passes through the false bottom under drain strainers to the outlet piping at the bottom of the Unit. When the unit’s capacity is exhausted, regeneration begins. The resin is backwashed and hydraulically classified based on their densities, and after the bed settles, regeneration is carried out. Caustic Sodium hydroxide is introduced through the down flow.

Regenerate distributor and acid is introduced through the up flow regenerator header. The interface collector receives spent acid and caustic for disposal. A slow rinse displaces regenerate acid and caustic, then the full bed is rinsed with service water. The vessel is drained until the water level is just above the bed surface. The resins are then re-mixed with air. The vessel is refilled and the bed is rinsed before the unit is returned to service.

Typical Applications:

  • Treatment of water pre-demineralised with ion exchange resins
  • Polishing of reverse osmosis permeate
  • Polishing of sea water distillate
  • Treatment of turbine condensate in power stations
  • Treatment of process condensate in various industries
  • Production of ultra-pure water for the semi-conductors-industry
